silicon controlled switch is electronic power components which can realize fast switching of the shunt capacitor. the control signal of the control circuit&controller adopt the photoelectric isolation so as to avoid disturbance. when the controller sends out switching signal, the thyristor is conducted/intercepted so as to input/switch the corresponding capacitor.

high speed real-time compensation:
it adopts the advanced technology of scr to replace the traditional electro---ic contactor operation&it is also collocated with advanced compensation instrument espe---lly designed for high speed on-off control. the thyristor control can easily reach 20ms within the investment compensation rate to meet the operati-onal requirements of any operation in pursuit of the ideal of reactive power compensation.
extending the lifetime of the capacitors:
because of the above excellent properties of zero-crossing switching, even it is at high-speed&frequent operation, the capacitor can still avoid the damage of insulation material caused by the traditional splitting-inrush transient, thereby affecting the service life.
no input inrush current:
it makes use of superior precision “zero crossing switching” controller, all capacitors are only input when the capacitor residual voltage is equal&synchronous to the system voltage, so there is no general common contactor, because of inrush current caused by difference of voltage, it avoids transient arc&its damage when the capacitor is input.
